Da war sie wieder, die lebhafte Diskussion über die Verwendung eines Data Vault Link-Satellite. Die Argumentation, ob ja oder nein, drehte sich im Kreis.

On July 15, Mathias Brink and I ran a webinar about Data Vault on EXASOL, modeling and implementation. The webinar started with an overview of the concepts of Data Vault Modeling and how Data Vault Modeling enables agile development cycles. Afterwards, we showed a demo that transformed the TPC-H data model into a Data Vault data model and how you can then query the data out of the Data Vault data model. The results were then compared with the original queries of the TPC-H.

PowerDesigner offers the possibility to edit the properties for a database in the so-called DBMS resource files. The DMBS resource files contain all information for PowerDesigner to generate DDL, DML and other SQL artifacts. For many databases, there are pre-built, included DBMS resource files for the different database versions.

PowerDesigner bietet die Möglichkeit, die Eigenschaften für eine Datenbank in der sogenannten DBMS-Ressourcendateien zu bearbeiten. Die DMBS-Ressourcendateien enthalten alle Informationen für den PowerDesigner, um DDL, DML und andere SQL Artefakte zu generieren. Für viele Datenbanken gibt es vorgefertigte, mitgelieferte DBMS-Ressourcendateien für die unterschiedlichen Datenbankversionen.

Months ago I talked to Stephan Volkmann, the student I mentor, about possibilities to write a seminar paper. One suggestion was to write about Information Modeling, namely FCO-IM, ORM2 and NIAM, siblings of the Fact-Orietented Modeling (FOM) family. In my opinion, FOM is the most powerful technique for building conceptual information models, as I wrote in a previous blogpost Sketch Notes Reflections at TDWI Roundtable with FCO-IM.

Liebe Leser und Leserinnen meines Blogs,

vor fünf Jahren ist eine lang gehegte Idee von mir Wirklichkeit geworden. Am 1. Juli 2017 erblickte TEDAMOH das Licht der Welt.

I, Stephan, am very happy that I'm invited to give a presentation at the Knowledge Gap 2020 in Munich.

My presentation is about advanced techniques in Fact-Oriented Modeling.

Often data models are built with a technical focus, because they need to be delivered fast or must meet various technical requirements. Therefore, the business aspect and the meaning of objects and relationships are swept under the table. But then the business domain later hardly understands the data model and has problems to work with it in own applications or reports – which often results in a redesign of the data model and renewed time and cost expenditures.

I was at the Data Modeling Zone Europe 2016 in Berlin as a speaker. It was the 4^th Data Modeling Zone in Europe and in my opinion one of the best per the conference program and the interesting and awesome chats with other speakers and attendees. This year’s venue was the Abion Hotel in Berlin, situated next to the Spreebogen and for this a great environment around the venue.

FastChangeCo^TM's data modelers keep experiencing the problem of lost mappings from views to tables in PowerDesigner.

I reactivated my Meetup Data Vault Interest Group this week. Long time ago I was thinking about a table of fellow regulars to network with other, let’s call them Data Vaulters. It should be a relaxed get-together, no business driven presentation or even worse advertisement for XYZ tool, consulting or any flavor of Data Vault. The feedback of many people was that they want something different to the existing Business Intelligence Meetings. So, here it is!

FastChangeCo and the Fast Change in a Hybrid Cloud Data Warehouse with elasticity

What is this 20 minute talk about at #BAS19?

The fictitious company FastChangeCo has developed a possibility not only to manufacture Smart Devices, but also to extend the Smart Devices as wearables in the form of bio-sensors to clothing and living beings. With each of these devices, a large amount of (sensitive) data is generated, or more precisely: by recording, processing and evaluating personal and environmental data.

Der PowerDesigner ist derzeit nur für das Betriebssystem Windows verfügbar. So weit, so bekannt. Amal Leyla Qasim, Datenmodelliererin im Data Management Center of Excellence (DMCE) Team, hat sich zum Ziel gesetzt, ihren Arbeitsplatz auf einen Apple MacBook umzustellen.

PowerDesigner is currently only available for the Windows operating system. So far, so familiar. Amal Leyla Qasim, a data modeler on the Data Management Center of Excellence (DMCE) team, has set her sights on switching her workstation to an Apple MacBook Air.

Tipps und Tricks rund um PowerDesigner

In loser Folge berichte ich hier über meinen Erkenntnisgewinn mit dem Datenmodellierungswerkzeug PowerDesigner. Für mich selbst ist diese Serie eine Art Tagebuch, eine Wissensbasis und das ‘Secret Spice’, in der ich meine Entdeckungen, meine für mich selbst dokumentierten Tipps und Tricks rund um den PowerDesigner festhalte: Für Probleme des oder mit dem PowerDesigner, die ich während der Bearbeitung von Aufgaben in der Datenmodellierung hatte.

Erwartet hier daher keine Neuigkeiten über das Datenmodellierungswerkzeug PowerDesigner selbst.

Natürlich, und wie immer, aus meiner persönlichen Sicht oder aus Sicht einer der Team-Mitglieder des Data Management Center of Excellence (DMCE) bei meinem liebsten Kunden: FastChangeCo!

Tips and tricks for PowerDesigner

In loose order I report here about my gain of knowledge with the data modeling tool PowerDesigner. For myself, this series is a kind of diary, a knowledge base and the 'Secret Spice', in which I record my discoveries, my tips and tricks around PowerDesigner documented for myself: For problems of or with PowerDesigner that I had while working on data modeling tasks.

So don't expect any news here about the data modeling tool PowerDesigner itself.

Of course, and as always, from my personal point of view or from the point of view of one of the team members of the Data Management Center of Excellence (DMCE) at my favorite customer: FastChangeCo!

Die Data Modeling Zone Europe 2014 ist zu Ende. Es waren zwei ereignisreiche Tage mit großartigen Sprechern und einem vollen Programm. In vier Tracks referierten namhafte Sprecher wie Dan Linstedt, Ronald Damhof, Martijn Evers, Karen Lopez und Rich van der Lans über Themen der Datenmodellierung, Big Data oder auch Industrie Datenmodelle.

Our 25th anniversary roundtable in Frankfurt with FCO-IM was a great success. Almost 90 registrations and more than 60 attendees is an unexpected outcome for a topic that is almost unknown in Germany. If you want to know what happened at the roundtable, read about it in my previous blog post FCO-IM at TDWI Roundtable in Frankfurt.

Bei FastChangeCo entwerfen die Datenmodellierer des Data Management Center of Excellence (DMCE) Teams zum Speichern von Daten immer wieder neue Datenbankobjekte. Eine der Datenmodelliererinnen im Team ist Xuefang Kaya. Wenn sie eine neue User Story/Aufgabe übernimmt, modelliert sie in der Regel mehrere Tabellen, deren Spalten und legt einen Datentyp für jede Spalte fest.
